14 people have been injured after a suspected gas blast in the basement of a five-star hotel in central London.
Last night's explosion at the Hyatt Regency Churchill hotel on Portman Square in the Marylebone area caused part of the building to collapse.
500 people were evacuated from the hotel and all guests and staff were accounted for.
Around 80 firefighters were on the scene, including appliances with specialist equipment to deal with collapsed buildings.
London Ambulance Service initially said 12 people were injured but later revised the figure to 14, including two men with leg wounds who were taken to hospital.
A further three people needed hospital treatment, while nine others were checked over at the scene and given the all-clear.
A Metropolitan Police spokesman said: "At about 11.40pm we were called to a suspected gas explosion at Portman Square.
"Officers are in attendance alongside the fire brigade and ambulance service. A small number of injured parties are being treated."
A spokesman for London Fire Brigade said the explosion is thought to have been caused by a gas leak.
Structural engineers have been called to assess the damage in the basement area.
